This 3 storey property in Londonderry city centre was affected by extensive dry rot. Stronghold Preservation were requested to carry out preservation treatments to address the dry rot, that became evident during a refurbishment and which had been caused by damp ingress via the roof.
Further Information
Dry Rot
The wall plates, joist ends, hidden timber binders and truss
ends that were embedded in the masonry, were found to be affected
by dry rot. Dry rot
fruiting bodies were observed also. Wet rot was also found in
timber plugs embedded in the masonry wall
Dry Rot Treatment
All timber observed to be affected with dry rot was
removed. A number of timber roof trusses and purlins were
infected with dry rot at the bearing ends. These timbers were
repaired using a timber resin splice
system. 'At risk' timbers were treated with a boron
preservative to provide additional protection from a further
outbreak of dry rot. Masonry in the area of the dry rot was
sterilised using a biocide treatment.
Woodworm
Evidence of an active woodworm infestation was found: all structural
timbers in the roof, first and second floors were sprayed with a woodworm
insecticide.
